An Act supporting and honoring Immigration and Customs Enforcement lawful detainments (SHIELD Act)

This bill requires Massachusetts local law enforcement agencies to comply with Immigration and Customs Enforcement (ICE) requests to detain individuals convicted or charged with specific serious offenses: aggravated felonies (e.g., murder, drug trafficking), violent crimes, gang offenses, or terrorism. It mandates holding these individuals for ICE custody if they meet any of these categories, or if an officer determines they pose a public safety threat. The law applies to all state, municipal, college, and university police departments, sheriffs' offices, and correctional facilities within Massachusetts. It creates a legal obligation for local agencies to honor these ICE detainer requests under defined circumstances.
